.To all whom it may concern:

Be it known that I, FREDERICK W. Gone, a citizen oi? the United States, residing at Newton Hi hlands, in the county of Middlesex and tate of Massachusetts, have invented an improvement in Signaling Devices, of which the following is a specification,

ln police and fire-signaling systems, it is often necessary to provide an electric signailing-device adapted to be arranged on a,

pole, post, or other support out of doors, where it is subjected to severe weather conditions, said device being employed to -give aloud aubible signal for the purpose oi. calling' the attention of a passing oilicer, or for signaling street trafic. The signaling-device may be electrically connected to be controlled by the electric signaling system and arranged to give a code-signal, corresponding with a signal-box number, or it may be arranged to give an intermittent or a simple continuous signal. It has been found that the ordinary automobile horn having a vibratory diaphragm is well suited to sound an alarm for this purpose, but the. device, as ordinarily constructed, is entirely unsuited to the required conditions, as it is not adapted to withstand the severe weather conditions to which it must be subjected.

This invention has for its object the con- 7 struction of an electric signaling-device embodying a vibratory diaphragm which is arranged in a protecting casing and especially adapting it for use out of doors, where it is subjected to severe weather conditions, without (lo-arrangement or injury, and also is adapted to be attached to a post, pole, or other support. The electric signaling-device embodying my invention may be employed for other purposes.

Figure 1 is a side elevation of a signaling device embodying this invention.

Fig. 2 is a transverse vertical section of the same.

Fig. 3 is a front view of the same.

10 represents a hollow case adapted to contain the vibratory diaphragm 11 which case has its outer face formed with a fiat seat for the attachment thereto of a horn 12, and said horn havin% a flat seat adapted for engagement with t e seat on the diaphragm case and to be secured thereto by screws, bolts, or other means to provide a tight weather-proof joint. Said horn is bent so that when the diaphra case is vertically disposed, as illustrated, said horn will be extended in a downward direction, see Fig. 1, thereby to prevent the rain, snow, sleet, etc., from entering The actuating-means for the vibratory diaphragm comprises a toothed wheel 15, and a shaft 16, bearing said wheel, which shaft may be the shaft oi an electric motor, and said motor is contained in a case 20, which is rigidly connected with the diaphragm case and is vertically disposed. The motor terminals 22, are extended outwardly from the side wall of the motor-case. An annular flange 23, is arranged on the outside of the motor-case, which, when said case is vertically disposed, occupies substantially a horizontal plane.

A pot 25 is arranged beneath the motorcase to inclose the motor terminals and thereby protect them from the weather, and said pot has a flat seat at the top, at 26. for the engagement of the flange 23, and "for connection therewith by suitable bolts or screws, so that the motor-case and parts connected therewith will be supported on said pot and will be rigidly connected with the pot by a tight joint. The pot has a bracket 30 formed integral with it orconnected to it, which is extended laterally from it and is adapted for attachment to a pole, post, or other support by means of screws or bolts, and said bracket is made hollow or provided with an interior recess 35, which is in open communication with, the interior of the pot, and there are provided vertical alined holes above and below said recess, which open thereinto, so that the leading-in wires may pass through one or the other of said holes to the motor terminals. Said holes are threaded to receive a proper threaded pipe, through which leading-in wires will pass, and a screw-plug 38, or equivalent closure will be employed to close either hole which is not being used by the pipe. This provides for leading-in wires which may be run either upward or downward, as the case may be, and a closure for the unused hole, thereby tightly closing the in and partly ot. It will be observed that the pot with its bracket supports the motor-case and parts connected therewith, and also incloses the, motor terminals, and thereby protects them from the weather.

I claim 1. A signaling device comprising a vibratory diaphragm,aninclosing casing therefor, actuating means including an electric motor, an inclosing casing therefor, means uniting said casings, motor terminals extended from said motorcasing at one end, said motor casing having an external annular flange intermediate the ends thereof, a pot having an annular seat on which said flange is received, whereby said motor casing is partly out of said pot and said motor terminals are inclosed thereby, said pot having a bracket extended from it adapted to be attached to a support.

2. A signaling device comprising a pot having a bracket by which it is adapted to be supported and an annular seat, an electric motor including a case having extended motor terminals thereon and an external annular flange above said terminals, said motor case partially extended .within said pot and said flange received on the annular sea-t thereof, a I vibratory diaphragm .arranged above said pot, means supporting said diaphragm from said motor case, and

'means to vibrate said diaphragm by said motor.

3. A signaling-device comprising a vibratory diaphragm, actuating-means therefor including an electric-motor, a case for said motor having a wall through which the motor terminals extend, a pot arranged to inclose and thereby protect the motor terminals having means adapted for supporting the motor-case, and having a bracket by eaasaa.

which it may be attached to a'support, said bracket havin a recess in open communication with the interior of the pot, and a pipe hole for the leading in wires opening mto said recess. '4. A signaling-device comprising a vibrw nals having means adapted for supporting the motor case, and having a bracket by which it may be attached to a support, said bracket havin a recess in open communication with t 3 interior of the pot, vertically-alined pipe holes in the bracket above and below the recess, and a closure adapted to enga e either hole, the other being'employed or the leading-in wires. 1 5. A signaling-device comprising a vibratory diaphragm, actuating-means therefor including an electric-motor, a case for said diaphragm, and a case for the motor, said cases being vertically disposed, and a downwardly extended horn connected with the diaphragm case, a pot arranged below the motor case adapted to inclose and thereby protect the motor terminals, and having a seat to support said motor case, said pot having a bracket with an opening for the leading-in wires, adapted to be attached to a support.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
